Sapphire Plug-ins for Open Fx: CloudsColorSmooth

Generates a full color clouds texture. Procedural noise texture is
independently generated for each of the red, green, and blue output
channels. The Shift Speed parameters cause the texture to automatically
translate over time.

In the Sapphire Render effects submenu.

Inputs:

Background:
Optional.
The clip to combine the clouds image with. This may
be ignored if the Combine option is set to Clouds Only.

Mask:
Optional.
Interpolate between the result and the Source input. White areas
use the result of the effect. Black areas use the Source clip.

Parameters:

Load Preset:
Push-button
.
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset:
Push-button
.
Brings up the Preset Save dialog to save a preset for this effect.

Blur Mocha:
Default:
0,
Range:
0 or greater.
Blurs the Mocha Mask by this amount before using.
This can be used to soften the edges or quantization artifacts of
the mask, and smooth out the time displacements.

Mocha Opacity:
Default:
1,
Range:
0 to 1.
Controls the strength of the Mocha mask.
Lower values reduce the intensity of the effect.

Invert Mocha:
Check-box, Default:
off.
If enabled, the black and white of the Mocha Mask
are inverted before applying the effect.

Show Mocha Only:
Check-box, Default:
off.
Bypass the effect and show the Mocha Mask itself.

Combine Masks:
Popup menu, Default: Union
.
Determines how to combine the Mocha Mask and Input
Mask when both are supplied to the effect.

Union:
Uses the area covered by both masks together.

Intersect:
Uses the area that overlaps between the two masks.

Mocha Only:
Ignore the Input Mask and only use the
Mocha Mask.

Frequency:
Default:
8,
Range:
0.01 or greater.
The spatial frequency of the clouds. Increase to zoom
out, decrease to zoom in. Very high values of Frequency are clamped
internally so the grain size is no smaller than a few pixels. If
you want even finer grain use S_Grain or S_Clouds:Perspective instead.

Frequency Rel X:
Default:
0.2,
Range:
0.01 or greater.
The relative horizontal frequency of the texture.
Increase to stretch it vertically or decrease to stretch it
horizontally.

Octaves:
Integer, Default:
1,
Range:
1 to 10.
The number of summed layers of noise. Each octave is twice
the frequency and half the amplitude of the previous. A single octave
gives a smooth texture. Adding octaves makes the result approach a
fractal (1/f) noise texture.

Seed:
Default:
0.6,
Range:
0 or greater.
Used to initialize the random number generator. The actual
seed value is not significant, but different seeds give different
results and the same value should give a repeatable result.

Shift Start:
X & Y, Default:
[0 0],
Range:
any.
Translation offset of the texture. Since the texture is
procedurally generated it can be shifted with no repeating units or
seams occurring. This parameter can be adjusted using the Shift Start Widget.

Shift Speed:
X & Y, Default:
[0.5 0],
Range:
any.
Translation speed of the texture. If non-zero, the
result is automatically animated to shift at this rate. The result
of animated Speed values may not be intuitive, so for variable
speed motion it is usually best to set this to 0 and animate the
Shift Start values instead.

Brightness:
Default:
1,
Range:
0 or greater.
Scales the brightness of the result.

Scale Colors:
Default rgb:
[1 1 1].
Scales the color of the result. For example, if it is yellow
[1 1 0], the blue of the result will be 0.

Saturation:
Default:
1,
Range:
0 to 10.
Scales the color saturation. Increase for more intense
colors. Set to 0 for monochrome.

Offset:
Default:
0,
Range:
-8 to 2.
Adds this gray value to the result (or subtracts if
negative). 0 has no effect, .5 is middle gray, and 1 is white.

Bg Brightness:
Default:
1,
Range:
0 or greater.
The background brightness is scaled by this value before
being combined with the clouds.

Combine:
Popup menu, Default: Screen
.
Determines how the texture is combined with the Background.

Clouds Only:
gives only the clouds texture with no Background.

Mult:
the texture is multiplied by the Background.

Add:
the texture is added to the Background.

Screen:
the texture is blended with the Background using a screen operation.

Difference:
the result is the difference between the texture and Background.

Overlay:
the texture is combined with the Background using an overlay function.

Mask Use:
Popup menu, Default: Luma
.
Determines how the Mask input channels are used to make a
monochrome mask.

Luma:
the luminance of the RGB channels is used.

Alpha:
only the Alpha channel is used.

Blur Mask:
Default:
0.05,
Range:
0 or greater.
Blurs the Mask input by this amount before using. This
can provide a smoother transition between the masked and unmasked
areas. It has no effect unless the Mask input is provided.

Invert Mask:
Check-box, Default:
off.
If on, inverts the mask input so the effect is applied
to areas where the Mask is black instead of white. This has no effect
unless the Mask input is provided.

Show Shift Start:
Check-box, Default:
on.
Turns on or off the screen user interface for adjusting the
Shift Start parameter.
